2 years ago I am going to answer 2 first.

Below is a modified form_table.rb example code that supports deletion with an X button (I am using Ruby 3.1 with support for the 3-dot ... operator).
Do not forget that with table data-binding, it is very simple to delete. As long as you delete an element from the data-bound array "self.contacts" (as known from this code cell_rows <=> [self, :contacts]), Glimmer DSL for LibUI will automatically reflect your change in the table control (the view). The code responsible for that is under the on_clicked listener on button_column with the logic self.contacts.delete_at(row) (deletes by clicked row index)
By the way, deleting a table row by selecting/right-clicking a row (as opposed to clicking X) or by checkmarking it does not work today (not on all platforms) due to limitations in LibUI, but I believe libui-ng is working on supporting these options in the future.
require 'glimmer-dsl-libui'
class FormTable
Contact = Struct.new(:name, :email, :phone, :city, :state, :delete) do
def initialize(...)
super(...)
self.delete = 'X'
end
end
include Glimmer
attr_accessor :contacts, :name, :email, :phone, :city, :state, :filter_value

Contact.new('Lisa Sky', 'lisa@sky.com', '720-523-4329', 'Denver', 'CO'),

FormTable.new.launchScreenshots where I click the X buttons one by one in random order.
1) Would it be possible to dump the current dataset into a .yml file and/or hash? This can happen on the commandline too. That way we can quickly copy/paste it. Or perhaps a .yml file, save it into a local file, so we can use that as a real contact form.
2) Would it be possible to also delete a row? Not sure how easy it is to do so; could simply be a button and a field with the field focusing on a number; or more elegantly perhaps the currently selected row will be deleted if a delete-button is clicked.
The example I refer to is the one provided in the main README e.g . with
